Is there a way to allow authenticated user to edit data stored in a custom SQL Connection.

Example: I have a table I am pulling data from and it is external to the Kentico database, still on the same server. I have a Repeater or Uni displaying all the data. I want some users to be able to click on a row and make updates to it.

Is there any objects(controls) pre-build to facilitate this or do need to build this all from scratch?

I know I can custom code this a ASCX / ASPX pages, but wanted to see if there was methods or controls I have missed.
